Data residency describes the geographic location where data is stored or otherwise maintained. A contract, customer policy or local rule may require certain data to remain in or be replicated within a specified country or region.
Which locations should be mapped?
- Primary application databases
- Backups, archives and disaster-recovery copies
- Logs, analytics and monitoring systems
- Support tools and file-sharing platforms
- Subprocessor infrastructure
- Developer or administrator access locations
Data residency vs. data localization
Residency states where data is located. Localization is a legal or policy requirement that certain data be stored, processed or controlled within a jurisdiction. Data sovereignty concerns the laws and authority that apply to the data. These concepts overlap but are not interchangeable.
Why does residency matter for a BPO?
A service team may work in one country while the application and backups operate elsewhere. Buyers should assess both infrastructure location and remote access, including subprocessors and business-continuity arrangements.
How should residency be verified?
Use architecture diagrams, provider region settings, contracts, subprocessor disclosures, audit evidence and access logs. A sales statement that a service is “hosted locally” may not cover backups, support access or ancillary tools.
What belongs in the operating record?
Record approved regions, restricted data types, transfer mechanisms, exceptions, responsible owners and review dates. Recheck the map when systems, vendors, support locations or recovery arrangements change.
